About the team

The Sensing Engineering team at Q-CTRL transforms quantum research into deployable technologies that address real-world problems. We design, build, and field-validate an array of quantum sensors that support our key products, including Ironestone Opal - our solution for GPS-denied navigation.

You don't need a background in quantum to make an impact here. We value strong engineering fundamentals, a product mindset, and a drive to solve the hardest engineering problems in quantum sensing today.

About the role

We are seeking an exceptionally skilled and intuitive Precision Mechanical Technician to join our fast-paced Quantum Sensing team. In this role, you will work across our cutting-edge Gravimetry and Magnetometry R&D; groups to turn high-level scientific concepts into physical reality.

This is not a production assembly line job. You will be working almost exclusively on custom, one-off or low volume prototypes and ultra-delicate assemblies. We need a natural problem solver-someone with outstanding mechanical intuition who thrives in an R&D; environment, handles high-stakes precision hardware with extreme care, and can figure out how to build complex systems even when step-by-step instructions don't exist yet.

Note on Quantum Experience:



You do not need a background in quantum mechanics or quantum hardware! We have world-class scientists to handle the physics-we need your exceptional mechanical craftsmanship to bring the hardware to life.

About Q-CTRL

Q-CTRL is the global leader in AI-powered quantum control infrastructure software. We build the tools that make quantum technology practical, solving the hardest challenges in quantum computing and quantum sensing to deliver real-world impact.

Founded in 2017, we operate globally with offices in Sydney, Los Angeles, San Francisco, Berlin, and Oxford. Our teams bring together technical and multi-disciplinary expertise across the product lifecycle, and we're hiring talent to help scale every part of the business. We work quickly to turn cutting-edge science into deployable technology.

In 2024 we raised US$113 million in Series B funding, the largest aggregate investment for a quantum software company. Six months later we delivered the first commercial quantum advantage with Ironstone Opal, our field-validated quantum navigation solution for defense and industry.

At Q-CTRL, we prioritize outcomes over hours. We offer flexibility, equity potential, and competitive benefits that reflect our high-performance culture. If you're ready to help shape the future of quantum, we'd love to hear from you!
